So I use hostgator, shared hosting, and it crashed today. I am on 1.8 (the latest, cannot get into see the exact version). Should I look for a new hosting provider, or dedicated hosting? I have optimized all the php settings, we generally have about a 100 question survey, with about 20,000 users but sometimes up to 100,000 users.



They wanted to know:


You may want to consult the LimeSurvey Documentation at docs.limesurvey.org/English+Instructions+for+LimeSurvey to see if caching is an option as well as general optimization suggestions.

Please note that the site (nhs2survey.org/limesurvey2/) was generating a 403 error message in a browser due to the following line in the .htaccess file at /home/nhs2/public_html

DirectoryIndex login.php

Is this set this way for a reason? Typically the default.html or index.php file should load. Is this set up this way for a reason? Should we revert the change?

OK, a 100 question survey with 20.000 - 100.000 respondents for sure is nothing for a shared hoster like hostgator. I think with this type of surveys you should even invest in a own dedicated server.

About the other aspects: I have no idea. But to me it doesn't look right. I don't think that this comes from Limesurvey, especially as it is in the public_html folder and your limesurvey installation is in the subfolder "limesurvey2".
